  Hi, I want to create an I-optimal custom DOE with 5 continuous factors and one categorical factor (with 2 levels). I also want to have 4 centre points which I specify on set-up. I also choose RSM for my model as I know there is curvature. When JMP creates the design, the centre points are not equally divided across the two categorical levels - one category gets 4 centre points and the other gets 2...

Does anyone know what specific type of tes...

  I have data from a dose-response experiment (pharmacology) to which I fitted a modified Michael-Menten model using non-linear regression (--> specialized modeling --> nonlinear (model = A*(1-exp(-k*dose))^c + intercept)). In this experiment the accent was put on testing many different levels; the number of observations for an individual level is limited (insufficient for a direct analysis of varia...
